I'm a fiber skeptic, too. IMO, it's the phytonutrients in the higher-fiber foods that deserve credit for positive health outcomes, not the fiber itself. It seems like "they" credited fiber almost arbitrarily.

And for a rant of my own... I hate the colon-cleanse scam artists who are proclaiming that 80% of people "suffer" from constipation, and/or 80% of health problems can be solved by using our magical laxatives... or something ridiculous like that.
